Begonia plant named ‘KRBELAT02’

ABSTRACT

A new and distinct cultivar of  Begonia  plant named ‘KRBELAT02’ characterized by its upright to broadly spreading and uniformly mounded plant habit; moderately vigorous growth habit; freely branching habit; showy leaves that are green and greyed green in color with centers that are flushed with red purple; and excellent postproduction longevity.

Botanical designation: Begonia hybrida.

Cultivar denomination: ‘KRBELAT02’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia hybrida, commercially referred to as a Rex Begonia and hereinafter referred to by the name ‘KRBELAT02’.

The new Begonia plant is a product of a planned breeding program conducted by the Inventor in Ermelo, The Netherlands. The objective of the breeding program is to create new Rex Begonia plants with unique and attractive leaf coloration.

The new Begonia plant originated from a cross-pollination made by the Inventor in Ermelo, The Netherlands in January, 2009 of a proprietary selection of Begonia hybrida identified as code number KV06B0370-002, not patented, as the female, or seed, parent with a proprietary selection of Begonia hybrida identified as code number KV07B0399-002, not patented, as the male, or pollen, parent. The new Begonia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Ermelo, The Netherlands in January, 2010. Asexual reproduction of the new Begonia plant by leaf cuttings taken in a controlled greenhouse environment in Ermelo, The Netherlands since February, 2010 has shown that the unique features of this new Begonia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Begonia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘KRBELAT02’. These characteristics in combination distinguish ‘KRBELAT02’ as a new and distinct Begonia plant:

-   -   1. Upright to broadly spreading and uniformly mounded plant         habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching habit.     -   4. Showy leaves that are green and greyed green in color with         centers that are flushed with red purple.     -   5. Excellent postproduction longevity.

Plants of the new Begonia differ primarily from plants of the female parent selection in leaf color as plants of the female parent selection have green and dark purple-colored leaves with whitish grey-colored spots. In addition, plants are more vigorous than plants of the female parent selection.

Plants of the new Begonia differ primarily from plants of the male parent selection in leaf color as plants of the male parent selection have green and purple-colored leaves with small purple grey-colored spots. In addition, plants are more uniform than plants of the male parent selection.

Plants of the new Begonia can be compared to plants of Begonia hybrida ‘African Jungle’, not patented. In side-by-side comparisons, plants of the new Begonia differ primarily from plants of ‘African Jungle’ in leaf color as plants of ‘African Jungle’ have green-colored leaves with purple grey-colored spots. In addition, plants of the new Begonia are more freely branching than plants of ‘African Jungle’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Begonia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Begonia plant.

The photograph on the first sheet comprises a side perspective view of a typical plant of ‘KRBELAT02’ grown in a container.

The photograph on the second sheet are close up views of the upper (top of the sheet) and lower (bottom of the sheet) surfaces of typical leaves of ‘KRBELAT02’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the late spring in 12-cm containers in a shaded glass-covered greenhouse in Ermelo, The Netherlands and under cultural practices typical of commercial Rex Begonia production. During the production of the plants, day temperatures averaged 20° C. and night temperatures averaged 18° C. Plants were ten weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
